.SH NAME
range_strinbuf \- range check for string in buffer
.SH SYNTAX
.B #include <libowfat/rangecheck.h>

int \fBrange_strinbuf\fP(const void* buf,size_t len,const void* stringstart);
.SH DESCRIPTION
range_strinbuf checks that the ASCIIZ-string starting at
\fIstringstart\fR starts and ends within the buffer
\fIbuf\fR[0..\fIlen\fR-1].

If the string is not 0-terminated but the length is known beforehand,
use range_arrayinbuf instead.
.SH "RETURN VALUE"
If the buffer is implausible (buf is NULL or buf+len has an integer overflow), return 0.

If \fIstringstart\fR points before or after the buffer, return 0.

If there is no '\\0' within the buffer, return 0.

Otherwise, return 1.
